PDF standard CJK font confusion

Hi,

I'm trying to embed Chineese, Japanese en Korean text in my PDF's. To avoid embedding the fonts (or font subsets), I am using the standard PDF fonts form Acrobat's font packs.

I did manage to get the text in, but the width of the character is all wrong. It must have something to do with the CIDSystemInfo or the Encoding, but I can't figure it out.

I am reading the widths from the AdobeSongStd-Light.otf font, and I am using the same widths for calculating the length of the text.

Below are some fragments of my PDF. If required, I can post the PDF as well.

It would be great if someone could point me into the right direction.

Regards, and thanks in advance,

Wiebe.
